We propose a new method to elicit individuals' risk preferences. Similar to Holt and Laury (2002), we use a simple multiple price-list format. However, our method is based on a general notion of increasing risk, which allows classifying individuals as more or less risk-averse without assuming a specic utility framework. In a laboratory experiment we compare both methods. Each classies individuals almost identically as risk-averse, -neutral, or -seeking. However, classications of individuals as more or less risk-averse dier substantially. Moreover, our approach yields higher measures of risk aversion, and only with our method these measures are robust toward increasing stakes. Minimize

In this paper we argue that the recent evidence on individuals' decision making is of high relevance for the measurement of poverty when switching from a static and certain to a dynamic and uncertain framework. The numerous proposed measures of multi-period poverty and vulnerability have until now not taken into account the insights from behavioural economics. Building on reference dependent utility models we propose a new measure of both (perceived) multi-period poverty and vulnerability, where the poverty status of an individual is not only a function of (expected) consumption levels but also of (expected) losses and gains in consumption. We demonstrate the implications of the proposed measures with a small illustrative example. Minimize

In this paper we propose a new method to elicit the intensity of individual's risk preferences. Our method uses a simple multiple price-list format and is based on the increasing risk definitions of Rothschild and Stiglitz (1970, 1971). We are thus able to classify individuals as more or less risk-averse without assuming an expected utility fram...

In this paper we propose a new method to elicit the intensity of individual's risk preferences. Our method uses a simple multiple price-list format and is based on the increasing risk definitions of Rothschild and Stiglitz (1970, 1971). We are thus able to classify individuals as more or less risk-averse without assuming an expected utility framework. In a lab experiment we directly compare our method to the well-known method of Holt and Laury (2002) and find that our approach yields higher estimates of relative risk aversion that are much closer to what is observed in the field.

The dominant background for observations of gamma-rays in the energy region above 50 GeV with Imaging Atmospheric Cherenkov telescopes are cosmic-ray events.

The dominant background for observations of gamma-rays in the energy region above 50 GeV with Imaging Atmospheric Cherenkov telescopes are cosmic-ray events. The images of most of the cosmic ray showers look significantly different from those of gamma-rays and are therefore easily discriminated. However, a small fraction of events seems to be indistinguishable from gamma-rays. This constitutes an irreducible background to the observation of high-energy gamma-ray sources, and limits the sensitivity achievable with a given instrument. Here, a Monte Carlo study of gamma-like cosmic-ray events is presented. The nature of gamma-like cosmic-ray events, the shower particles that are responsible for the gamma-like appearance, and the dependence of these results on the choice of the hadronic interaction model are investigated. Most of the gamma-like cosmic ray events are characterised by the production of high-energy pi0's early in the shower development which dump most of the shower energy into electromagnetic sub-showers. Also Cherenkov light from single muons can mimic gamma-rays in close-by pairs of telescopes. Differences of up to 25% in the collection area for gamma-like proton showers between QGSJet/FLUKA and Sibyll/FLUKA simulations have been found. ; Comment: Accepted by Journal of Astroparticle Physics Minimize

This thesis examines the concept of ‘embeddedness’ as condition and strategy in contemporary art and cultural production. Identifying embeddedness as a motif of contextual proximity and a strategy in contemporary art, the thesis proposes immediacy to be the result of intrinsic mediation. The project’s main concern is how embeddedness is contextualised by the current conditions that authors and cultural producers engage with. The primary question is whether and how embeddedness can convey a critical relation to the mediation that it undertakes. These concerns inform and arise from my work as an artist, and my participation in events, some of which I organise. The project claims that embeddedness in art is a critical condition and an editorial concept or a strategic plan that can be set up by the artist. The investigation begins by looking at conditions of embeddedness by focusing on concepts of subjectivity and by elaborating strategies that I call ‘auto-direction’. For example, concepts of subjectivity are taken up in relation to Richard Serra’s video Boomerang (1974), in which the performer Nancy Holt reflects on her own spoken words, which are fed back with a short delay via microphone and headphones into her ears. Auto-direction, introduced with the example of Steven Spielberg’s initiative of a video diary exchange project between Israeli and Palestinian children, describes the activity of the producer, who self-directs his situated presence. Taking up idioms of embeddedness from artists like Phil Collins, Christian Jankowski and Erik van Lieshout the project examines embeddedness through a comparative analysis between contemporary art, visual culture, media theory, sociology, art theory, psychoanalysis and philosophy. These practices lead to an identification of embeddedness as an author’s immanent exposure, a claim taken up through analysis of theoretical texts and literature by Rosalind Krauss, Jacques Lacan, Jacques Derrida, Gregory Bateson, Hal Foster, Bernard Williams and Alfred North Whitehead.

The success of antibody-based drugs has led to an increased demand for predictive computational tools to assist antibody engineering efforts surrounding the six hypervariable loop regions making up the antigen binding site. Accurate computational modeling of isolated protein loop regions can be quite difficult; consequently, modeling an antigen binding site that includes six loops is particularly challenging. In this work, we present a method for automatic modeling of the FV region of an immunoglobulin based upon the use of a precompiled antibody x-ray structure database, which serves as a source of framework and hypervariable region structural templates that are grafted together. We applied this method (on common desktop hardware) to the Second Antibody Modeling Assessment (AMA-II) target structures as well as an experimental specialized CDR-H3 loop modeling method. The results of the computational structure predictions will be presented and discussed. Minimize
